A Study of Urodynamics on Neurogenic Bladder / 대한비뇨기과학회지

ABSTRACT

A study of urodynamics including simultaneous cystometry/rectal pressure/electromyography and simultaneous urethral profilometry/ electromyography on neurogenic bladder was performed in the Department of Urology, Seoul National University Hospital during the period March, 1980 through July, 1980 and the following results were obtained; 1. Of 13 cases, 2 cases were hyperreflexis and 11cases were areflexia on cystometry. On cystometry and urethral electromyography, detrusor sphincter dyssynergia was observed in 1 case of hyperreflexia and 2 cases of areflexia. In 1 case of detrusor sphincter dyssynergia having areflexia voiding cystourethrography was performed under the fluoroscopy in standing position and the site of dyssynergia could be detected. On cystometry and rectal pressure monitoring, the true detrusor pressure could be obtained through electronic subtraction (total bladder pressure minus rectal pressure.) . 2. Of 13 cases, maximum urethral closure pressure was below the normal value in 6 cases of areflexia but functional urethral length was normal in all cases on urethroprofilometry. On urethroprofilometry and urethral electromyography, it was found that the difference of the distribution existed in the urethral sphincter between the both sexes.
